AUTOMATIC HAY-PRESS.

Specification of Letters Patent.

Patented Oct. as, race.

To all whom it may concern:

' Be it known that I, ARIES C. LAUGI-ILTN, a citizen of the United States, residing at Alta Loma, in the county of Galveston and State of Texas, have invented new and useful Improvements in Automatic Hay-Presses, of which the following is a specification.

This invention relates to presses, and more particularly to those adapted for use in forming hay or like material into and has for an object to provide a press of this character with a plurality of compression chambers, and means for alternately feeding material into said chambers.

A further object of the present invention is to provide a simple form of hopper into.

which material may be fed, and from which the material will be delivered to a blower-to be automatically carried to thecompression chambers.

Another object of this invention is to provide novel means to be alternately operated to provide a chute-forming element. so that material to be operated upon can at all F times be eifectively discharged into its respective compression chamber.

Another ob ect of this invention is to provide a chute-form1ng element which may be actuated by the compression plungers, and

to arrange said means so that upon return movement of one plunger material can be fed into the chamber in which the compression plunger is on its downward stroke.

A still further object is to provide novel mechanism for imparting to the compression plungers recipiimitory movement, providing for movement of said plungers in opposite directions.

A still further object is to provide a driven shaft which may be operated by a suitable motor, and which willv supply power for operating the blower, the material feeding belt therefor, and the plungers.

Other objects and advantages will .be apparent as the nature of the invention is better disclosed, and it will be understood that changes within the specific scope of the claims may be made without departingfrom the spirit of the invention.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate like parts of the several views, Figure 1 is a side elevation of my irn. proved hay press. Fig. 2 is a horizontal section taken on the line 2?2 of Fig. 1. Fig. 3 is a vertical section taken on the line 33 of bales,

horizontally disposed shaft 26 Fig. 1. Fig. 4 is a horizontal section taken on the line 4?4 of Fig. 1. Fig. 5 is a top plan view of the blower casing showing the means for driving the fan. Fig. 6 is a vertical section taken on the line 6..6 of Fig. 1. Fig. 7 is a detail perspective view of one of the plunger engaging blocks. Fig, 8 is a detail perspective view of the modified form of the forming element. Fig.9 is a view similar to Fig. 6 showing a slightly modified form of chute-forming element. Fig. 10 is a detail perspective view of-the chute-form in element shown in Fig. 9.

eferring now more particularly to the drawings, there is shown a hay press 1 comprising a wheeled frame which preferably consists of a bottom 2 having parallel side members 3 and 3, and intermediate similar members 4 and 5 which latter members form with the former members chambers 6 and 7 as clearly shown in Figs. 2 and 6 of. the drawings.

Alining bearings 8 are supported upon the press just described. and these bearings, as shown, receive a horizontally disposed driven shaft 9 provided preferably midway between its ends with a driving pulley 10 which may be belted to a' suitable motor, not illustrated. Forwardly of the bearings 8, the members i and 5 support a countershaft 11 provided at its ends with gear wheels 12 and 13 in mesh with pinions let upon the shaft 9. A plun-- ger 15 of the form usually employed in presses of this character is mounted in the chamber 7, and .is provided with a piston rod 16 loosely connected to the gear wheel 13. A similar plunger 17 is located in the chamber 6 and is connected by a pistonrod 18 to the gear wheel 12. The piston rods 16 and 18 respectively are connected to the gear wheels 1.2 and 13 in such. manner that upon rotation of the shaft 9 the plungers'will be rcciprocated inopposite directions for a purpose to be hereinafter more fully described.

A casing 1.9 of cylindrical form is disposed directly above the shaft 11, and this casing is provided witha vertical shaft 20 to which is secured a hub 21 having radial spokes 22 to which are secured fan blades 23. The shaft 20, is provided at the upper end. thereof with a beveled gear wheel 24: in mesh with a similar gear wheel 25 carried by a journaled in bearings 27 upon the top of the casing 19. The shaft 26, is provided at its outer end with a pulley 28, and the shaft 9 is provided with a pulley 29 so that a belt30 passed over said pulleys 28 and 29 will effectively rotate the shaft 26, and consequently revolve the shaft 20. The casing 19 is provided with a slot 31,, and a suitably inclined rack 32 is supportedin any suitable manner to the easing and has its lower end disposed directly in line with the slot 31 as clearly shown in Fig. 3 of the drawings. The rack 32 is provided with parallel spaced side members 33, and between these side members adjacent to their inner ends is journaled a transverse shaft 34 having a roller 35 secured thereto. A similar shaft 36 is located adjacent to the rear of the rack 32 and has its ends journaled in the members 33,-and this shaft supports a roller 37 identical in construction to the-roller An endless belt 38 is passed over the rollers 35 and 37 and carries a plurality of slats 39. As shown, the belt has one lead thereof always spaced from the bottom of the rack 32.' The rack 32 supports at its outer end a. hopper 40 into which material may be placed and fed between the bottom of the rack 32 and one lead of the belt so that material to be operated upon can be effectively carried in a novel manner to the casing 19. The casing is connected with one end of a conveyor tube 41, and as shown clearly in Fig. 1 of the drawing the said tube discharges into a chute 42 having a vertically disposed throat 43, and a lower enlarged discharge end 44 disposed directly above the chambers 6 and 7 of the press.

An oscillatory arm 45 is pivotally mounted at 46 to a bracket 47 between the members 4 and 5, and this arm, at its upper end is provided with cars 48 and 49, the ear 48 having pivotally connected thereto a -chute forming element 50 adapted to lie at times in parallel relation with respect to the wall 51 of the portion 44 of the chute, and the car 49 has pivotally connected thereto a chute forming element 52, adapted to lie at times in parallel relation with respect to-the wall 52 of the chute 44. The chute-forming elements 50 and 52 respectively are also adapted to lie at times in-a vertical position and at right angles with respect to the bottom 2 of the press, and when in those positions they lie in rabbeted portions 53 of the members 4 and 5 which rabbeted portions open into the chambers 6 and 7. The arm 45 is provided, at the lower end thereof with right angularly 'disposed fingers 54 and 55, the finger 54 being provided with a portion 56 adapted to'he at times in parallel relation with respect to the bottom of the members anddirectly beneath the chamber 6, and the tingci' 55 is provided with a ;-ortion 57 identical to the portion 56 and is adapted to lie at times in parallel relation beneath the bottom of the tness and directly.beneath the, chamber 7. The chamber 6 is provided with a plunger operated 4 block 58 having adepending stem 59 formed press, but it will of course. be understood that it may be secured at any suitable'point for accolnphshin the desired end. The

chamber 7 is PIOVldBd Wltll a block 63 iden .tical in every detail to the block 58 but] adapted to be held elevated in a similar manner as that already described by the provision of a spring 64. The blocks 58 and- 63 are prefera portions 65 so that the plungers will more ly provided with beveled effectively depress said blocks as will be understood. Y I

The shaft 34 which supports the roller35' for the belt 38 is preferably provided with a pulley 66, and as shown, the shaft 9 is pro vided with a pulley 67 so that a belt 68 engaged with pulley 67 and with the pulley 66 effectively revolves the shaft 34 to drive the belt 38. r a

1 In the modified form of my invention shown in Figs. 9 and 10, I provide a chuteforming element 69 having a weightedupper end 70, and a depending portion 71 piv oted as shown at 72 to a deflector member 73. The portion 71 or arm as it may be called is provided at its lower end with fingers 74 ferred form of my invention. The fingers 74 and 75 are operated by the Vertical sliding blocks 58 and 63 previously described. The form of elements shown in Fig. 8 is similar to that shown in Figs. 9 and 10, but" the ele'ment 7 6 is preferably constructed from a flat reetangularplate having a depending arm 77 with oppositely directed fingers 78 and 79 at its lower end. In other respects the element 7 6 is identical, and its operation is the same as that previously referred to Figs. 9 and 10.

' In operation of the press, power is'sup. plied to the shaft 9 to revolve the-same so that the plungers, as stated, may be reciprocated in oppositedirections, and so that the belt 38 may be operated to feed material from the hopper 40 into the fan casing 19, and to also supply power to the shaft 26 to rotate the fan. As soon as material reaches the passage 31 formed in the casin 19 it will be blown into the tube 41 and disc arged into the chute 42. Assumin the plunger15 to be at the forward end 0 the throat, the" sliding block 63 will be depressed'as shown in Fig. 6 of the drawings, and incidentto the movement of the plungeragainst said sliding block, the block will be carried down wardly suddenly and will engage the portion 57 of the stem 59 to knock the arm 45 so that turns to the sion chambers,

it will assume an inclined position with re spect to the bottom of the press, causing the element to lie in parallel relation with respect to the wall 51 of the chute so that the said material to be pressed will be discharged into the chamberfi to be operated upon by the plunger 17. Then the plunger 15 reposition shown in Fig. 2, the plunger, 17 will operate its sliding block 58 to throw the arm 45 in a reversed position so that the chute-forming element 52 will assume a position parallel with respect to the wall 52 in order that material may be discharged into the chamber 7 and operated upon by the plunger 15'.

' A press constructed as herein set forth and described is extremely simple, is arranged in a compact manner and may be operated at a minimum expense, utilizing little power, and will effectively serve the purpose intended.

'Having thus described my invention what is claimed as new, is:

1. A press having a plurality ofcompression chambers, plungers operating in said chambers, means for conveying material to the compression chambers, and a plunger operated chute forming element adapted to alternately deflect material into the said chambers.
